HEATING-DRUM.

SPECIFICATION forming part of Letters Patent No. 364,112, dated May31,1887.

Application tiled February 3, 1887. Serial No. 226,407. (No model.)

T (1. whom, it may concern:

Be itknown that I, HEINRICH P. HEITMANN, a citizen of the United Statesof America, residing at Ableman,'in the county of Sank and State ofWisconsin, have invented certain new and useful Improvements inHeating-Drums; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being bad to the accompanying drawings, and to lettersof reference marked thereon, which form a part of this specification.

This invention relates to heating-drums for stoves, and is designed asan improvement on the stove illustrated in United States Letters PatentNo. 333,856, issued to me January 5,

The improvements will be described in detail in the followingspecification, and the novel features and combinations pointed out inthe claims.

In the accompanying drawings, Figure 1 is a diagrammatic viewillustrating the relation between a heatingstove and drum, shown insection, and a stove remote from "said drum. Fig. 2 is a horizontalsection taken on line 00 x at the left hand of Fig. 1. Fig. 3 is asimilar section taken on line y 3 Fig. 1, just above the slidingdampers.

The heater Bin apartment A may be a stove of any preferred form -as, forinstance, the cook-stove shownand is to be fitted with a pipe, I),communicating with the chimney.

Within another apartment, A, is a heatingstove, G, from which the topplate or cap is removed and replaced by a drum consisting of an outershell, 1), openat the bottom and closed at the top, and an innerhorizontal chamber, D, formed by walls d, extending from side to side ofthe outer shell and terminating in openings therein. These openings inthe outer shell are closed by doors d, to permit of closing the chamberD at both ends, and affording access thereto when desired.

Near the top ofthe drum is a stove-pipe collar, E, from which a pipe, 0,leads .to the chimney, and at a point just below the bottom wall ofchamber D is connected another pipe, F, leading from pipe I) of heaterB. The

.pipe e.

passage leading to collar E is fitted with a damper, E, a damper, f,being also arranged in pipe F. At a pointjust below pipe F, and parallelwith the bottom wall of chamber D, is secured a support-plate, G, narrowguides g 9 being arranged a little above this support G at each end.Between the support G and guides g are arranged two horizontalslidedampers, II H, so proportioned that both may lie upon support G, toleave the passages g and g at each side of the support open, or beadjusted to close one or both of said passages g g, each damper beingprovided with an operating-rod, h h, extending out beneath pipe F, bywhich the proper adjustments of said dampers H H may be made.

Pipe b is provided at a point above its junction with the branch pipe Fwith a damper, b, by means of which said pipe I) may be closed.

In practice it is designed that a fire will be constantly maintained inheater B, which represents the kitehen-range in a dwelling, so thatwhen'it is desired to but slightly modify the temperature in apartment Athe damper b may be closed, damper 'f opened, slide dampers H H adjustedtoclose the passages g 9', leading from the heater 0 to the drum, anddamper E opened, thereby causing the heated products of combustion tocirculate through the drum and pass to the chimney through In colderweather, however, when the heat derived from range B is insufficient toheat apartment A, the damper f will be closed, damper I) opened,slide-dampers H H adjusted to open the passages g g, and a fire bemaintained in heater 0. Should the fire in heater'O render the apartmenttoo warm, the damper E may be closed and the damper f opened, thusconducting the heated products of combustion from the fire in heater 0through pipe F, and to the chimney through pipe b.

The chamber D may be used as an oven for heating various articles; orthe doors (I may be thrown open to permit the heat in said chamber toescape into apartment A.

The drum is preferably constructed of sheet metal, and may be made tofit any usual form of stove, whether a wood or coal burner. Indeed, inmany instances the heat received from range B and radiated from the drumwill be found sufficient to heat an apartment, as A,

at all times, and the heater C may be dispensed with. In such cases thevarious dampers will be arranged as first herein described.

To provide for the removal of soot and fine ashes that may lodge in thedrum after passing damper E, I arrange within the drum a soot-box, I,leading downward from the space behind said damper, a door, 71, beingarranged at the lower end of said soot box, to aiford access thereto.

I claim- 1. A heating-drum consisting, substantially as described, of anouter shell provided at one end .with an exit and a damper for closingsaid exit and at the other end with passages, slidedampers traveling inguides to open and close said passages. and an opening above saidslidedampers to afford communication with a stove or range.

2. A hcating'drum consisting, substantially as described, of an outershell provided at the bottom with a. horizontal support, withslidedampers and an opening above said support, and having an exit anddamper at the top, a heating-chamber extending from side to side of theshell, and doors secured to the shell for closing both ends of theheating-chamber.

3. In combination with a stove or range having a main pipe and a branchleading there- 0 from, both fitted with dampers, and a heater in anotherapartment, a drum consisting of an outer shell provided at top with adampered exit leading to a chimney and at the bottom with passagesleading from the heater, slidedampers to open and close said passages,and an opening above said dampers to afl'ord communication with thebranch pipe from the range, substantially as described.

4. In combination with a stove or range having a main pipe and a branchleading there- 0 from, both provided with dampers, and an independentheater, a drum consisting of an outer shell provided at the bottom withpassages leading from the heater and at the top with a dampered exitleading to the chimney, and at a point above the passages with anopening communicating with the branch from the range, slide-damperstraveling in guides to open or close the passages, a heating-chamber,the open ends of which terminate in openings at opposite sides of theshell, and doors fitted to said shell to' close both ends of theheating-chamber, substantially as described.

In testimony whereof I aflix my signature in presence of two witnesses.

HEINRICH P. HEIIMANN.
